Webmcp Kit — Development skill for Claude Code

WebMCP Kit

Make your website or web app agent-ready. WebMCP Kit is a coding-agent plugin that adds [WebMCP](https://github.com/webmachinelearning/webmcp) tools to your site or application, so browser agents can act through your app's own logic instead of scraping the page.

It reads your repo, proposes a tool plan, **waits for your approval**, implements the tools with [`@nekuda/webmcp-sdk`](https://www.npmjs.com/package/@nekuda/webmcp-sdk), and verifies them in a real browser. Everything runs locally — **your code never leaves your machine**; there is no hosted scanner.

Works with **Claude Code** and **Codex**.

Install

**Claude Code**

/plugin marketplace add nekuda-ai/webmcp-kit
/plugin install webmcp-kit@nekuda

**Codex**

codex plugin marketplace add nekuda-ai/webmcp-kit
codex plugin add webmcp-kit

Or run `/plugins` inside Codex and install it from the browser there.

On Codex, installing also registers the plugin's lifecycle hooks (`PreToolUse`/`Stop`) — they only ferry feedback from the live review UI back to the agent, and you can inspect them anytime with `/hooks`.

Package for the OpenAI Platform

Build the skills-only ZIP accepted by the OpenAI Platform plugin uploader:

python3 scripts/package-openai-skills.py

The archive is written to `dist/webmcp-kit-.zip`. It includes the Codex manifest, brand assets, and both skills, and leaves out repository files and the lifecycle hooks used by the full marketplace install.

Prerequisites

• Claude Code or Codex
• A website or web app you can run locally — any stack, the plugin adapts
• Bun (optional) — powers the live review UI; without it you review the plan in chat
• Chrome 150+ with the WebMCP flag enabled (chrome://flags) — used to verify tools in a real browser

Use

Open your repo in your agent and ask it to make your website or web app agent-ready (in Claude
